CR
I think it has something to do with the aircraft being used for a job it was not designed for, at least with the military maintenance schedule.
I agree 100% on the decissions made by the kiwi gov on that issue.
I understand it's a great deal for companies but as a pilot, enjoy much more flying civilian certificates and maintained on those standards than Restricted maintained on Army standards doing civilian production work.
All that is personal and MHO.
Buen vuelo
